MAINTENANCE PROCEDURE

“13-C”: CCH C-Level Infinite Loop Failure (Temporary)

(1)Meaning

The system message “13-C” indicates that C-level infinite loop for PM (Port Microprocessor) within a CCH/ CCT circuit card has occurred less than 16 times within an hour. When the number of the fault occurrence time is less than 8, the Phase 1 restart is executed.

If the number of fault occurrence time is 8 to 16, the Phase 3 restart is executed.

(2)Related System Message

When the C-level infinite loop failure occurs more than 15 times, the specific PM of CCH/CCT is placed into make-busy state and the system message “13-B” is output.
